Indonesia weather & when to go: June

Indonesia June weather overview

The tables are now fully turned with the western and central Indonesian islands now getting all the attention, with Bali, Komodo, Lombok, Flores, Java and the Gilis expecting sunshine and little if any rain throughout June. Sulawesi is also expecting good weather. The islands further to the east - such as West Papua & Raja Ampat and the Moluccas - are now starting to receive more rain. If you’re visiting Indonesia in June you can expect clear, warm waters and an abundance of marine life, especially in the Komodo National Park and around the Gili Islands. Favourable diving conditions can be enjoyed across the Indonesian islands.

June’s weather in detail

NB: the westernmost point of Indonesia is a full 3200 miles from the eastern most tip, so it should come as no surprise that summarising the weather is not straightforward. The tables above split the ‘country’ (made up of 17,508 islands) into two regions - the western & central islands and the eastern islands (that sit to the east of the Wallace Line), however we encourage you to read the more detailed summaries below as there can be significant variations in conditions between the islands within each group.

Java

As Indonesia steams full speed towards its peak season, visitor numbers begin to increase across Java in June. May's good weather continues into June and the dry season gathers pace with only the occasional afternoon rain shower to break the hours of sunshine. Favourable trekking conditions continue on the mountains of Bromo and Ijen. Average temperatures hover around 30 °C, but are cooler in the more mountainous regions in East Java. June is a great time to visit Java for those wanting to avoid the peak crowds of the coming two months. 

Bali

June is one of the best months to visit Bali – the sunshine is set at max and it's blue skies all the way with average temperatures of 27°C. As it's not 'high season' as yet, visitor numbers are fairly low, so restaurants and beaches are not crowded and hotel deals can be had. As the month drawers to an end a sea breeze freshens the air during the evenings and temperatures drop slightly. 

Nusa Tenggara

Lombok, Flores, Komodo National Park, Sumba

June is one of the best months of the year to visit Lombok & the Gili Islands, Flores & Sumba. Days are typically warm and sunny throughout the region with pleasant average temperatures of 25-27°C and relatively low humidity levels. It’s another great month for diving off the coast of Lombok, the Gili Islands and in the Komodo National Park, and trekking continues on Lombok's Mt Rinjani.

Sumatra

June is the hottest month of the year in Medan and North Sumatra: maximum temperatures of 33°C and 34°C are the norm and the temperature at night hovers around (a warm) 24°C. Palembang and the southern regions are slightly cooler, although highs of 32°C are not uncommon. Across the island, days are hot and sunny and rainfall is minimal, although is still possible in the northern jungle regions, such as Bukit Lawang. 

Kalimantan

Throughout Kalimantan the light rains of the previous months come to an end in June, replaced predominantly by hot, sunny days. Rain showers are still possible (particularly in the forested regions) but these will come in the form of a short, sharp shower in the late afternoon. Average temperatures remain around 28-29°C, humidity levels are high, and maximum temperatures of 32°C are a regular occurrence. If you plan on visiting Tanjung Puting National Park you have a higher chance of spotting orang-utan during dry season. 

Sulawesi

Hot, sunny days continue throughout Sulawesi in June. Rainfall should still be expected in north Sulawesi (including the city of Manado), but Toraja and the southern regions are much drier. Humidity continues to drop but average temperatures remain around 28-29°C, and maximum temperatures of 32°C are a regular occurrence. June ia a beautiful time to be trekking in Maros & Bantimurung, as the rice fields and forests are lush & green following months of rain.

West Papua & Raja Ampat

June is typically one of the wettest months of the year across the islands of Raja Ampat, although it doesn’t rain all day, every day. Rainfall usually comes in the form of short, sharp, localised showers. By mid-June the wind will also pick up across Raja Ampat. Strong winds can make for bumpy boat journeys or even cancellations on small boats. June is also typically one of the wettest months of the year to visit Wamena and the Baliem Valley.

The Moluccas

June is one of the wettest months of the year in the central Molucca islands of Ambon and Seram, and skies are typically overcast. Strong winds and rainfall occur in the Banda Islands during June which can affect boat transfers. However, the southern and northern Molucca islands are basking in sunshine during June, with little chance of rain.
